Sometimes hasColorSupport() in Symfony\Console..StreamOutput returns false even if there is color support, to make it explicitly know we must call this method before output eg. in fire()
/**
* Execute the console command.
*
* @return mixed
*/
public function fire()
{
// set color support explicitly
$this->getOutput()->setDecorated(true);
$this->error('Im Colored error');
$this->info('Im colored info');
$this->comment('Im colored comment');
}
